At this time, a U-shaped channel will be formed in the middle of the lower cover 12 and the upper cover 11. When water enters from the gap, it will flow in the U-shaped channel, making it difficult to enter the interior. At the same time, the opening and closing of the upper cover 11 and the lower cover 12 will contact the sealing strips 14 on both sides of the middle frame 1. At this time, waterproofing can be performed from the outside. Through the above structure, the middle frame 1 is provided with the upper cover 11 and the lower cover 12 to cooperate with the vertical plate 13. A U-shaped channel can be formed in the upper cover 11 and the lower cover 12 to reduce the entry of water into the interior. At the same time, the sealing strip 14 can be sealed from the outside to reduce the flow of water into the U-shaped channel. Through the cooperation of the two, the overall sealing and waterproofing effect can be improved.

[0026] like Figure 1 and Figure 4 As shown, a pair of placement grooves 2 are provided at the bottom of the lower cover 12, and the inner side walls of the pair of placement grooves 2 are rotatably connected to support plates 21, and a pair of limit rods 22 are fixed to the inner side walls of the placement grooves 2. The limit rods 22 are correspondingly arranged with the support plates 21. During operation, when the power adapter is placed in an indoor environment, the support plates 21 can be rotated to approach the limit rods 22. When the limit rods 22 contact the support plates 21, the position of the support plates 21 can be supported. At this time, the support plates 21 are in an inclined state, and then the support plates 21 are contacted with the floor or table in the room. At this time, the support plates 21 can lift the entire body for a distance. When water flows on the floor or table, it will pass through the bottom of the lower cover 12. Through the above structure, the placement grooves 2, the support plates 21 and the limit rods 22 are provided, so that the entire body can be raised a distance from the ground or table, which can reduce the contact of the water flow power adapter, thereby reducing the situation of internal water ingress, and at the same time reduce the wear between the lower cover 12 and the table or floor, and improve the stability of the position of the entire body when placed.

[0027] like Figure 4As shown, a square groove 3 is provided at the bottom of the lower cover 12. The square groove 3 is arranged on the side away from the support plate 21. A push plate 31 is slidably connected in the square groove 3. A pressure plate 32 is fixedly connected to the side wall of the push plate 31. A spring 33 is fixedly connected to the inner side wall of the square groove 3. The end of the spring 33 is fixedly connected to the side wall of the push plate 31. A fixing rod 34 is fixedly connected to the side wall of the support plate 21. When working, when the support plate 21 is retracted, the support plate 21 is rotated to enter the placement groove 2. At this time, the push plate 31 can be pulled to make the pressure plate 32 away from the fixing rod 34. When the support plate 21 enters the placement slot 2, the push plate 31 is released. At this time, the spring 33 will rebound and drive the pressure plate 32 close to the fixing rod 34. At this time, the pressure plate 32 will clamp the fixing rod 34 to fix the support plate 21 in the placement slot 2. Through the above structure, the push plate 31 and the pressure plate 32 are arranged to cooperate with the spring 33 and the fixing rod 34, which can facilitate fixing the position of the support plate 21 when the support plate 21 is retracted, so as to reduce the situation where the support plate 21 is separated from the placement slot 2 after being retracted.

[0028] like Figure 1 and Figure 2 As shown, a pair of fixing strips 4 are fixed to the side walls of the middle frame 1, and a side panel 41 is fixed to the side wall of the fixing strip 4. When working, the fixing strip 4 is fixed to the surface of the middle frame 1 by welding or bonding. At this time, two upper and lower channels are formed between the side panels 41 and the middle frame 1, and then glue can be poured in the channels. The two ends of the side panels 41 must exceed the connection between the upper cover 11, the lower cover 12 and the middle frame 1. After glue pouring, the middle frame 1 and the upper cover 11 and the lower cover 12 can be sealed. Through the above structure, the setting of the fixing strip 4 and the side panels 41 can form two channels on the surface of the middle frame 1, so that glue can be poured in the channels to seal the middle frame 1 with the upper cover 11 and the lower cover 12, so as to improve the overall waterproof effect.

[0029] like Figure 2 As shown, a sealing frame 5 is fixedly connected to the end of the middle frame 1, and the sealing frame 5 is arranged corresponding to the wiring port 15. During operation, when the connecting line of the electronic device is connected to the power adapter through the wiring port 15, the inner wall of the sealing frame 5 will contact the surface of the connecting line. Through the above structure, the sealing frame 5 is provided to seal the connecting line of the electronic device and the wiring port 15, so as to reduce the situation where water enters the interior from the connection, thereby improving the overall waterproof effect.

[0030] like Figure 3As shown, the side wall of the sealing frame 5 is fixed with a slide rail 6, and a bidirectional screw 61 is rotatably connected in the slide rail 6. A pair of sliders 62 are threadedly connected to the middle part of the bidirectional screw 61, and a clamping plate 63 is fixed to the bottom of the slider 62. During operation, after the connecting line of the electronic device is connected to the power adapter, the bidirectional screw 61 can be rotated to drive the slider 62 and the clamping plate 63 to move in opposite directions. When the bidirectional screw 61 rotates forward, it will drive the clamping plates 63 closer to each other, thereby clamping and fixing the connecting line between the clamping plates 63. When the connecting line needs to be removed, the bidirectional screw 61 is rotated in the opposite direction to drive the clamping plate 63 away from the connecting line. Through the above structure, the bidirectional screw 61, the slider 62 and the clamping plate 63 are set, and the connecting line of the electronic device can be clamped and fixed to reduce the situation where the connecting line falls off from the power adapter.

[0031] like Figure 4 As shown, a plurality of anti-slip grooves 7 are provided in the middle of the push plate 31. During operation, when the push plate 31 is moved, it will contact the anti-slip grooves 7 on its surface. Through the above structure, the provision of the anti-slip grooves 7 can increase the friction force when in contact with the push plate 31, thereby improving the stability when the push plate 31 is moved and reducing the occurrence of slipping.

[0032] Working principle: When assembling the power adapter, the internal components are encapsulated inside by cooperating with the middle frame 1, the upper cover 11 and the lower cover 12. At this time, the vertical plates 13 on both sides of the middle frame 1 will be inserted into the card slots of the lower cover 12 and the upper cover 11. Then, the middle frame 1 will be connected to the upper cover 11 and the lower cover 12 by bonding or welding. At this time, a U-shaped channel will be formed in the middle of the lower cover 12 and the upper cover 11. When water enters from the gap, it will flow in the U-shaped channel, making it difficult to enter the interior. At the same time, the opening and closing of the upper cover 11 and the lower cover 12 will be close to the middle frame 1. When the power adapter is placed in an indoor environment, the support plate 21 can be rotated to approach the limiting rod 22. When the limiting rod 22 contacts the support plate 21, the position of the support plate 21 can be supported. At this time, the support plate 21 is in an inclined state. Then, the support plate 21 is made to contact the floor or table in the room. At this time, the support plate 21 can be raised as a whole for a distance. When water flows on the floor or table, it will pass through the bottom of the lower cover 12. When the support plate 21 is folded up, the support plate 21 is rotated to enter the place. The support plate 21 is placed in the slot 2, and the push plate 31 can be pulled to move the pressure plate 32 away from the fixing rod 34. When the support plate 21 enters the placement slot 2, the push plate 31 is released. At this time, the spring 33 will rebound and drive the pressure plate 32 close to the fixing rod 34. At this time, the pressure plate 32 will clamp the fixing rod 34 to fix the support plate 21 in the placement slot 2, and the fixing bar 4 is fixed to the surface of the middle frame 1 by welding or bonding. At this time, two upper and lower channels will be formed between the side plate 41 and the middle frame 1, and then glue can be poured in the channels, and the ends of the side plate 41 must exceed the upper cover 11 and the lower cover At the connection between 12 and the middle frame 1, the middle frame 1 and the upper cover 11 and the lower cover 12 can be sealed after glue is poured. After the connecting wire of the electronic device is connected to the power adapter, the bidirectional screw 61 can be rotated to drive the slider 62 and the splint 63 to move in opposite directions. When the bidirectional screw 61 rotates forward, the splints 63 will be driven to move closer to each other, thereby clamping and fixing the connecting wire between the splints 63. When the connecting wire needs to be removed, the bidirectional screw 61 is rotated in the opposite direction to drive the splint 63 away from the connecting wire. When the push plate 31 is moved, it will contact the anti-slip groove 7 on its surface.
